 This is Nate Adams with Energy Smart Home Performance and I'm going to show you around kind of an usual adicare. So you can see right there, right there, that is the tub up here. This was in addition down to a very old house. This house was originally built in 1842 and then this got put on. But it must have been a plumbing leak or something. They opened this up and this bathtub had a lot of trouble with the frozen pipes. We're going to stretch and fabric across this and turn it into a wall with some foam and get that sealed up. A few other things to note up here. Old houses routinely have open wall cavities, which is what these are. So that's where you're actually looking down inside the wall. So that's going to get tackled as well. And then out at the edges, we have to deal with the top plates. That's the top of the wall right there. And if you ever see boards like this across the ceiling, the odds are very good that there is an air leak hiding underneath there. So that's going to get hit as well. So there's a lot of air sealing work to do in here and this house really needs it. It's one of the leakiest ones that I've tested. So it's going to be fun to watch the results from this one.
